PCI: iproc: Convert PCI scan API to pci_scan_root_bus_bridge()

Browse Source 
The introduction of pci_scan_root_bus_bridge() provides a PCI core API to
scan a PCI root bus backed by an already initialized struct pci_host_bridge
object, which simplifies the bus scan interface and makes the PCI scan root
bus interface easier to generalize as members are added to the struct
pci_host_bridge.

Convert PCI iproc host code to pci_scan_root_bus_bridge() to improve the
PCI root bus scanning interface.
